EUGENE E. ALLEN, 035 LOS ANGELES, CALIFORNIA.

HYDROGARBON-BURITER.

Application filed December 12, 1912' To all whom it may concern:

' Be it known that I, EUGENE E stman, a citizen of the United States, residing at the city of Los Angeles, in the county of Los Angeles and State of California, have 'invented new and useful Improvements in Hydrocarbon-Burners, of'which the following is a specification.

My invention relates to that class of hydrocarbon burners in which a fluid hydrocarbon such as crude petroleum is commingled with an expansible fluid such as steam or heated air to heat and partially atomize it and then projected through a tip or tips into a combustion chamber and there lighted to produce heat and the object thereof is to produce an eflicient burner for that purpose. I accomplish this object by the burner described herein and illustrated in the accompanying drawings forming a part hereof in which:

Figure 1 is a side elevation of my improved burner partly in section, in place in a furnace, which is partly broken away. Fig. 2 is a diagrammatic representation of a modified form of burner.

In the drawings 1 is the hydrocarbon liquid supply line which is connected to the pressure pump, 2 which forces the liquid fuel into tank 3 through line at which line is provided with a regulating cock 5. An outlet pipe 6 extends from near the bottom of tank 3 out of the top thereof, and runs to and connects with the mixing chamber 7. Pipe 6 is provided with a regulating valve 8.

9 is a furnace chamber under boiler 10.

From the steam dome 11 of the boiler the steam pipe, 12,'runs to pump 2. From pipe .12 a branch 13 runs into and through tank 3 and coils within the tank around the outlet pipe 6 so as to heat the fluid. Branch 13 is provided with a regulating cock 1%. A second branch 15 leads into the mixin chamber 7. Within chamber 7 is the same arrangement as in mixer G of my Patent Number 834,701, dated October 30, 1906, and the construction and operation of this chamber is the same as the mixer of that patent and for that reason I do not specifically describe the same herein. Branch 15 has aregulating cook 16. Below branch 15 is a diaphragm regulator 17. Below regulator 17 Specification of Letters ratent.

, i is a gage 18. Below the gage is a regulating valve 19. Leading from chamber 7 is the mixture pipe 20' which runs into furnace chamber 9' and terminates in a burner tip 21. Near,the front wall of the furnace, pipe 20 is provided with a branch 22 which extends downwardly and inwardly and then upwardly and outwardly and terminates in a tip 23 which is in front of and above tip 21. These tips are so arranged that the discharge of one tip is angularly disposed as to the discharge of the other tip. The upper tip is preferably arranged to direct its discharge at right angles to the other tip. v

By having the fuel heated and partially atomized it can readily be divided and discharged into the furnace through one or' more tips.

By using two tips and having them discharge angularly toward each. other the position of the flame in the furnace can be easily regulated. The impinging of one jet upon the other jet completely atomizes the fuel and a better fire is produced than can be produced from a singletip. By projecting the branch pipe downwardly and inwardly and upwardly and outwardly the mixture passing through the branch pipe is superheated. The distance of the ti s and the angle of impingement of the mixture issuing therefrom is determined by theposition in the firebox that it is desired to have hottest, as the hottest flame will be produced where the power of one jet is equaled by that of the other jet.
